Environmental hazards such as exposure to heat, high humidity and limited air flow can cause heat stress. Contributing factors may also include the worker’s hydration level, clothing and physical exertion.

For those working outside on these hot days there are some steps to take to help reduce heat stress: drink plenty of water; limit sun exposure, especially between 11 a.m. and 4 p.m. when UV rays are at the strongest; cover exposed skin with loose-fitting, tightly-woven clothing; wear a wide-brimmed hat; have adequate ventilation in the workplace; take breaks in the shade or an air-conditioned space, if possible, and keep everyone safe by providing adequate supervision using a buddy system to watch for signs of heat stress in co-workers. Early detection is critical.

Those who experience the initial heat stress need to remove themselves from the environment, drink water, monitor the symptoms and advise someone in case they need further assistance or medical treatment.
